摘　　要：为了提高数据采集的精度和速率,设计了高精度、多通道的数据采集与显示系统。为了精准实现多通道数据采集与显示功能,使用赛灵思公司的Zynq-7000系列芯片以及AD7606完成多通道数据采集与显示。在设备软件设计方面,A/D转换完成后存入DDR3存储器,然后采用AXI4总线与可编程逻辑(PL)部分通信,最后通过ARM驱动完成数据的实时显示。经实验证明,该系统可以良好地实现16通道的数据采集功能。In order to improve the accuracy and speed of data acquisition,a highprecision,multichannel data acquisition and display system is designed.In order to accurately realize the multichannel data acquisition and display function,the Zynq-7000 series chip of Xilinx company and AD7606 are used to complete the multichannel data acquisition and display.In terms of equipment software design,after A/D conversion is completed,it is stored in DDR3 memory,then AXI 4 bus is used to communicate with programmable logic(PL),and finally the realtime display of data is completed through ARM drive.The experiment shows that the system can well realize the 16 channel data acquisition function.
